21. Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. Unlike in- toeing, out-toeing may lead to pain and disability as the child grows into adulthood. 30. To rule out any subsequent SCFE of the contralateral hip, we further assessed the status of the femoral growth plate at the time of CT and at latest follow-up. Clinical Orthopaedics and Related Research. In our cohort, femoral neck version was asymmetrically decreased (-2 13 versus 7 11) and the prevalence of femoral retroversion was higher (58% versus 29%) in hips with SCFE than in the healthy contralateral side (Table 3). The Hip Disability and Osteoarthritis Outcome Score (HOOS) (Klassbo et al., 2003; Nilsdotter et al., 2003), was administered to determine level of hip-specific functional disability in the CHJP group. The mean age was 15 4 years, 48% (38 of 79) of the patients were male, and 56% (44 of 79) were obese (defined as a BMI > 95th percentile (mean BMI 34 9 kg/m2). It has been reported that some degree of remodeling of the femoral head-neck junction can be expected after fixation of the epiphysis over time [1, 9]. Paired t-tests including Bonferroni corrections for repeated measurements were performed for comparison between the mean femoral version angles. Limb Lengthening and Complex Reconstruction Service, out-toeing or "duck walk" walking with the foot pointed outward instead of straight ahead. 17. First, we included patients who had previous in situ fixation and presented with a symptomatic SCFE deformity as well as patients who had not undergone any surgical treatment for SCFE. To date, the best treatment strategy in patients with symptomatic SCFE deformity is not known because of a lack of comparative studies with long-term follow-up [2, 47]. to call, please leave a message and we will return your call. By continuing to use this website you are giving consent to cookies being used. The I-bars represent the corresponding 95% CI. In hips with SCFE, we found excellent agreement (intraclass correlation coefficient [ICC] > 0.80) for intraobserver reproducibility (reader 1, ICC 0.93 to 0.96) and interobserver reliability (ICC 0.95 to 0.98) for all five measurement methods. MR imaging measurement of the femoral antetorsional angle as a new technique: comparison with CT in children and adults. Historically, severe and moderate SCFE deformities leading to symptomatic femoroacetabular impingement have been treated with an extraarticular approach by means of an intertrochanteric osteotomy [16, 41]. A Type I error rate of 5% was used. Of the 754 patients diagnosed with SCFE between 2000 and 2017, 172 patients had undergone pelvic CT scans. and Reikers et al. Symptoms of femoral retroversion may include: If femoral retroversion is suspected, a doctor will do a physical examination of the legs and hips in addition to a thorough medical, developmental and family history. In anatomy, the word "version" refers to the angle or rotation of all or part of an organ, bone or other structure in the body, relative to other structures in the body. 2018;38(suppl 1):S5-S12. [30]: -4 16) (Fig. Purpose. To the best of our knowledge, there are no normal reference values for CT-based femoral neck version measurements in children. In some cases, hip/femoral retroversion may be combined with a separate torsional deformity, such as a rotation in the tibia. 2013;95:e341-348. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. 6 It is the angular A study of children in Michigan. We showed that femoral neck version is asymmetrically decreased in unilateral SCFE, and that differences increase when including the femoral heads center. The present study evaluated, using an integrated vascular approach, changes in structure and function of the common carotid and femoral arteries (CCA and CFA) after prolonged head-down tilt bed rest (HDTBR). 20. The condition is usually congenital, meaning children are born with it. External tibial torsion. If the individual also has a separate rotational bone deformity such as internal tibial torsion an inward rotation of the tibia (shinbone) then femoral retroversion becomes even more difficult to diagnose. For both the SCFE side and contralateral side, we found an increasing prevalence of femoral retroversion when the more-proximal landmarks were selected (Table 3). Clin Orthop Relat Res. Wylie JD, Beckmann JT, Maak TG, Aoki SK. [35], Tomczak et al. Hello friends, thankyou for watching my video, I am Physiotherapist with masters degree and working as Associate Professor in Mangalore.I love to teach and p. Femoral neck version was measured as the orientation of the femoral neck. Top-view illustrations of excessive femoral retroversion. Femoral retroversion | definition of femoral retroversion by Medical dictionary femoral retroversion Also found in: Dictionary, Thesaurus, Encyclopedia. Clin Orthop Relat Res. Federal government websites often end in .gov or .mil. In this type of surgery, the femur bone is cut through a portal and an intramedullary rod is inserted into the marrow cavity of the bone. CLINICAL FEATURES Symptoms Will cause out-toeing and may lead to disability and decrease physical performance. Lee YS, Oh SH, Seon JK, Song EK, Yoon TR. 37. The state of being turned or tilted back. Subcapital osteotomy of the femoral neck for patients with healed slipped capital femoral epiphysis. . The data table on the chart reports the mean SD. The effect of modality and landmark selection on MRI and CT femoral torsion angles. 2021 May 1;479(5):960-961. doi: 10.1097/CORR.0000000000001704. Coxa vara. Akiyama M, Nakashima Y, Kitano T, et al. Femoral retroversion causes hip impingement, similar to the impingement and posterior instability that occurs in total hip arthroplasty. Balakumar B, Flatt E, Madan S. Moderate and severe SCFE (slipped capital femoral epiphysis) arthroscopic osteoplasty vs open neck osteotomy-a retrospective analysis of results. These side-by-side differences increased up to -22 (according to the method of Murphy et al. Exclusion criteria were bilateral SCFE in 31% (38 patients), any contralateral hip condition in 1% (one patient), and previous femoral osteotomies in 4% (five patients). Z Orthop Ihre Grenzgeb. New York, NY 10021 In this position, the femoral head is not positioned normally in the hip joint. femoral retroversion (___ degrees), femoral retroversion (physical finding), femoral retroversion, Femoral retroversion. At times, pure femoral retroversion may be the only source of hip impingement. The mean overall femoral version angles increased for hips with SCFE using more-distal landmarks compared with more-proximal landmarks. Background: Furthermore, the sample sizes in these studies that compared femoral version between the affected and unaffected hip in patients with unilateral SCFE were small. In anatomy, the word version refers to the angle or rotation of all or part of an organ, bone or other structure in the body, relative to other structures in the body. The definition of the proximal reference axis differs among the five methods. Southwick WO. [] reported an association of SCFE and femoral retroversion.More recently, many studies have shown an association . We performed a retrospective, controlled, single-center study at a tertiary pediatric care center and included patients with SCFE treated between 2000 and 2017. This procedure may be done for children over age 10 and adults and has a quick and reliable recovery. Femoral retroversion is a condition in which the femoral neck is rotated backward in relation to the femoral shaft. 32. More specifically, the prevalence of femoral retroversion was higher in hips with SCFE for the proximal methods of Lee et al. However, future studies are needed to investigate the value of different measurement methods in predicting the surgical outcome in patients with SCFE undergoing different procedures. 3). Unable to load your collection due to an error, Unable to load your delegates due to an error. Combined Imhauser osteotomy and osteochondroplasty in slipped capital femoral epiphysis through surgical hip dislocation approach. We performed a subgroup analysis, and with the numbers available, we observed any differences in femoral version angles between patients with and without previous in situ fixation (Table 5). where does bone formation occur during endochondral ossification? HHS Vulnerability Disclosure, Help The femoral vein is the major deep vein of the lower extremity. . To rule out this potential bias, we measured leg abduction angle on coronal scout CT views between a line connecting the femoral head with the center of the femoral condyle relative to the neutral line connecting the tip of the coccyx with the pubic symphysis. Femorln retroverze. For the diagnosis of this condition, conventional AP pelvic radiographs may represent a reliable, easily available diagnostic modality as they can be obtained with a reproducible technique allowing the anterior and posterior acetabular rims to be visible for assessment. The classic radiographic parameters to characterize femoroacetabular impingement secondary to SCFE include the slip angle and alpha angle measured on radiographs [28]. Femoral retroversion is also often called hip retroversion. your express consent. Contact Dr. Jarman, DPM Phoenix Podiatrist. The exact cause of femoral retroversion is unknown. Acetabular retroversion has been proposed to contribute to the development of osteoarthritis of the hip. and Reikers et al. Conclusion: SELECTED PROCEEDINGS FROM THE 2020 BERNESE HIP SYMPOSIUM GUEST EDITOR: KLAUS-ARNO SIEBENROCK MD. This yielded a mean side-by side difference of -8 11 (95% CI -11 to -6; p < 0.001) and a higher prevalence of femoral retroversion in hips with SCFE (58% [95% CI 47% to 69%]; p < 0.001) than on the contralateral side (29% [95% CI 19% to 39%]). Rebello G, Spencer S, Millis MB, Kim Y-J. femoral retroversion synonyms, femoral retroversion pronunciation, femoral retroversion translation, English dictionary definition of femoral retroversion. And if left untreated into adolescence, these abnormal femoral rotations can also contribute to the degeneration or arthritis of the hip. Because the lower part of the femur is connected to the knee, this also means that the knee is twisted outward relative to the hip. Tnnis D, Heinecke A. Acetabular and femoral anteversion: relationship with osteoarthritis of the hip. 12. J Pediatr Orthop. Femoral version by measurement method and by side (affected versus contralateral) was summarized using the mean, SD, and 95% confidence interval. 7. grip" deformity) and relative retroversion of the femoral head were dened as the cause of cam-type FAI, with worse long-term clinical and radiographic results. Wolters Kluwer Health If the individual also has a separate rotational bone deformity such as internal tibial torsion an inward rotation of the tibia (shinbone) then femoral retroversion becomes even more difficult to diagnose. Although femoral retroversion has been linked to the onset of slipped capital femoral epiphysis (SCFE), and may result from a rotation of the femoral epiphysis around the epiphyseal tubercle leading to femoral retroversion, femoral version has rarely been described in patients with SCFE. J Bone Joint Surg Am. J Bone Joint Surg Am. Furthermore, the prevalence of actual femoral retroversion and the effect of different measurement methods has yet to be studied in SCFE. The aim of the current study was to obtain precise normal values of the femoral anteversion angle using computed tomography on cadavers of mature dogs with normal hip joints of . Bali K, Railton P, Kiefer GN, Powell JN. We also compared isolated femoral neck version with aligning the orientation of the femoral neck with the femoral head center to define the proximal reference, as described by Reikers et al. The .gov means its official. 5 Femoral version, also referred to as femoral torsion, is another morphologic variable being investigated. Bone Joint J. Oduwole KO, de SA D, Kay J, et al. In hips with SCFE, there was a mean difference of -13 9 (95% CI -15 to -12; p < 0.001) between femoral neck version and Reikers et al.s [35] method, which reflects femoral neck orientation relative to the femoral heads center (Table 4). 2012;28:965-971. All ICMJE Conflict of Interest Forms for authors and Clinical Orthopaedics and Related Research editors and board members are on file with the publication and can be viewed on request. femoral anteversion decreases on average 25 degrees during this time as well Presentation Symptoms anterior knee pain caused by patellofemoral malalignment Physical Exam thigh-foot axis measurement best way to evaluate tibial torsion average during infancy is 5 degrees internal rotation, that slowly derotates This yielded a mean side-by side difference of -8 11 (95% CI -11 to -6; p < 0.001) and a higher prevalence of femoral retroversion in hips with SCFE (58% [95% CI 47% to 69%]; p < 0.001) than on the contralateral side (29% [95% CI 19% to 39%]). The most significant clinical implication of femoral retroversion is that it is not soft tissue-related. Clin Orthop Relat Res. [19] and Tomczak et al. 2023; 12(3):751. https: . 1956;88:3-41. Novais EN, Hosseinzadeh S, Emami SA, Maranho DA, Kim YJ, Kiapour AM. 1, 7, 9 It becomes apparent when the prewalking. What Is the Association Among Epiphyseal Rotation, Translation, and the Morphology of the Epiphysis and Metaphysis in Slipped Capital Femoral Epiphysis? Japanese. Pritchett JW, Perdue KD. Femoral anteversion occurs in up to 10 percent of children. 519 East 72nd St., Suite 204 Analogously, we found excellent agreement (ICC > 0.80) for intraobserver reproducibility (reader 1, range 0.91 to 0.96) and interobserver reliability (range 0.89 to 0.98) for all five measurement methods in healthy contralateral hips. The prevalence of femoral retroversion was high in patients with SCFE and increased when using proximal anatomic landmarks. However, Koerner et al. to -22 13 (95% CI -25 to -19; p < 0.001) according to the method of Murphy et al. 2017;11:284-288. The mean femoral neck version was lower on the SCFE side than on the contralateral side (-2 13 versus 7 11; p < 0.001) (Table 3). See this image and copyright information in PMC. 11. 39. Liu RW, Armstrong DG, Levine AD, Gilmore A, Thompson GH, Cooperman DR. An anatomic study of the epiphyseal tubercle and its importance in the pathogenesis of slipped capital femoral epiphysis. This procedure may be done for children over age 10 and adults and has a quick and reliable recovery. A comprehensive analysis of femoral version may provide valuable baseline information to optimize surgical planning in hips with sequalae of SCFE and to allow standardization of studies investigating surgical correction of SCFE deformities. In the remaining four patients with an open femoral growth plate at last clinical visit, radiographic follow-up was longer than 18 months (median 22 months, range 21 to 25), an observation period by which more than 90% of the subsequent contralateral SCFE reportedly occur [25]. "Of key note on the 3D studies," says Dr. Kamath "is the low femoral version 2.2 degrees, which is relative retroversion of the femur, when compared to normative female populations of this age." Her diagnosis? Mechanical risk factors for SCFE include rapid growth spurts, femoral retroversion, and femoral neck shaft angle. These differences between hips with SCFE and the contralateral side were higher and ranged from -17 11 (95% CI -20 to -15; p < 0.001) based on the method of Tomczak et al. Symptoms of femoral retroversion usually begin with the visual recognition of the rotated femur. Thus, this should not jeopardize the results of our study to a relevant degree. J Orthop Trauma. Femoral retroversion is common in early infancy and is caused by external rotation contracture of the hip secondary to intrauterine packing. Femoral anteversion causes the child's knees and feet to turn inward, or have what is also known as a "pigeon-toed" appearance. Please try after some time. Cartilage is a semi-rigid but flexible avascular connective tissue found at various sites within the body. A subset of patients was measured twice by the first obsever as well as by a second orthopaedic resident (JRK, 2 years of experience) to assess intraobserver reproducibility and interobserver reliability. Limb Lengthening and Complex Reconstruction Service may email you for journal alerts and information, but is committed In other words the knee is excessively twisted inward relative to the hip. Retroversion refers to an abnormal backward rotation of the hip relative to the knee. Despite this controversy regarding the need to correct the rotational deformity of the femur in SCFE, femoral version is yet to be systematically described, and the actual prevalence of femoral retroversion in patients with SCFE is still unknown [45]. the axis of the femoral neck is oriented more posteriorly than the distal reference line connecting the dorsal border of the femoral condyles. J Bone Joint Surg Am. One radiology resident (6 years of experience) measured femoral version of the entire study group using five different methods. Many children are born with femoral anteversions that they eventually grow out of. We found that femoral neck version is asymmetrically decreased by -8 in unilateral hips with SCFE compared with contralateral hips. Journal of Clinical Medicine. 2014;96:1119-1123. You may be trying to access this site from a secured browser on the server. He may also order an. This means thehip is twisted backward (posteriorly) in relation to the knee. Ethical approval for this study was obtained from the institutional review board of Boston Childrens Hospital (protocol number IRB-P00018761). Int Orthop. 2017;21:487-506. 34. Among these, the greatest differences were between the most-proximal methods and the more-distal methods, with a mean difference of -19 7 (95% CI -21 to -18; p < 0.001), comparing the methods of Lee et al. 15. Doing so may better inform surgeons as they contemplate when to use isolated offset correction or to perform an additional femoral osteotomy for SCFE correction based on the severity of the slip and the rotational deformity. The prevalence of femoral retroversion was high in our study and ranged from 47% to 91%, depending on the applied measurement method (Table 3). Passive hip range of motion predicts femoral torsion and acetabular version. However, in excessive cases, surgery may be needed to correct the rotation. 3. [19]) compared with distal landmarks to define the femoral reference axis (47% for the method of Tomczak et al. What is femoral anteversion? . Clinical features include an abnormal gait and pain with prolonged weight-bearing. 1973;55:1218-1224. Coxa valga and antetorta increases differences among different femoral version measurements : potential implications for derotational femoral osteotomy planning. 2018 Apr;476(4):890-899. doi: 10.1007/s11999.0000000000000127. Most proximally (Lee et al. In many cases, the child may grow out of it. Twenty-nine percent (23 of 79) of patients had no previous surgical treatment for SCFE. Thus, we compared femoral version angles and the prevalence of femoral retroversion in hips with SCFE with the unaffected contralateral side and among different measurement techniques. Bethesda, MD 20894, Web Policies However, an excessive femoral retroversion can place stress on hip and knee joints, often leading to joint pain and abnormal wear. 44. Schmaranzer F, Kallini JR, Miller PE, Kim Y-J, Bixby SD, Novais EN. This surgery includes cutting and realigning the femur. This work was performed at the Department of Orthopaedic Surgery, Boston Childrens Hospital, Harvard Medical School, Boston, MA, USA. Future studies should compare femoral version in SCFE hips to age-matched volunteers without a history of hip disease. Femoral Retroversion. The site is secure. It becomes apparent as the child starts to stand or cruise between 6 and 9 months. Bone Joint Res.
